GOIVIPANY, OF KEV] YORK,

H. Y., A CORPORATION OF NEW JERSEY ADHESIVE-TAPE Rotten Application filed February 4, 1927. Serial no. 165,789.

This invention relates essentially to a machine for reeling and unreeling adhesive tape which is used for surgical purposes: to bind cuts, wounds or sprains and it fundamentally 5 comprehends means for mounting one or a series of spools: on a. rotary shaft.

An object of the invention is to provide devices whereby the spools can be easily slipped off the shaft so that a. length of the tape can be quickly unwound in case it is required to bandage a wound.

Another object of the invention is to pro vide means associated with the rotary means for preventing the spools from sliding off the 5 shaft when it is rapidly rotated.

Another object of the invention is to provide the sleeve of each spool with a device for engaging the adhesive end of the tape without puncturing the same.

The invention resides more particularly in the novel combinations hereinafter described and claimed, reference being made to the accompanying drawing in which:

Fig. 1 represents a side elevation of a machine embodying this invention.

Fig. 2 is an end elevation of the same.

Fig. 3 is a vertical section taken along the lines 33 of Fig. 1 showing the tape engaged by the sleeve.

Fig. 4 is a. horizontal section taken along the line as of Fi g. 3 the shaft having been omitted.

In the drawing the numeral 5 designates a base having a vertical column 6 extending upwardly from the base and provided with a horizontal hub 7 projecting at right angles from the column. The base can be fastened to a table or other convenient article. The hub is equipped with a bore to support the reducod end 8 of a revolvable shaft 9 the enlarged portion of which is arranged to extend from the hub. The shaft is operated by means of a crank 10 fixed to its reduced end and the shaft can be rotated in the direction of the arrow as indicated in Fig. 2. The

rotate the shaft in either direction the pawl is swung out of engagement with the ratchet as indicated in dotted lines in Fig. 2. The foregoing way of mounting the shaft provides space for it to freely rotate in the bore and at same time it cannot be pulled out of the The portion of the shaft extending from the hub is of larger diameter than the portion journaled in the hub and it has a. groove 14 forming an inclined plane from the forward end of the shaft to the hub. On this shaft is arranged one or a number of spools each having a. tubular sleeve 15 with an indentation 16 to engage the groove whereby the spool is keyed to the shaft. The spools can be of different sizes as shown in order to wind thereon various widths of tape 17 having an adhesive surface.

In winding the tape on the spool the adhesive surface of the tape at its end as indi cated in Fig. 3 is pressed about a stud 18 formed by bending a portion of the sleeve outward. The end of the tape is thus firmly held to prevent it from slipping off the sleeve at the beginning of the winding operation. This mode of fastening the tape does not injure it by punctures so that all the tape can be utilized and it provides an easy method of unwinding the tape to its end.

When the shaft is rotated the spools have a tendency to centrifugally slide toward the unobstructed end of the shaft, but in view of the inclined groove coacting with the keyed spools this movement will be equalized or neutralized and the spools will remain in the positions they are placed on the shaft. The free and unobstructed end of the shaft offers a simple method of sliding the spools on and off without removing the shaft from its bearings or displacing any fastening devices, while the inclined plane prevents the spools from sliding off the free end of the shaft when it is rapidly revolved.

I claim:

1. A tape roller comprising a base having a vertical column provided with a horizontal hub, a shaft rotatively supported in the bore of the hub, a crank fixed to one end of the shaft the other end being free and unobstructed, said shaft having an inclined groove from the unobstructed end to the hub for keying one or a number of spools made to slide toward the hub by the rotation of the shaft and from the unobstructed end by the operator When the shaft is stationary.

2. A tape roller comprising a base having a vertical column provided with a horizontal hub a shaft having a reduced portion rotatively supported in the bore of the hub, a crank fixed to the reduced end of the shaft the other end being free and unobstructed, said shaft having an inclined groove from the unobstructed end to the hub for keying one or a number of spools adapted to slide toward the hub by the rotation of the shaft and from the unobstructed end by the 0perator when the shaft is stationary.

In testimony whereof I have hereunto set my hand.

EDWARD JOHNSON.
